This invention relates to water closet combinations of the siphon jet type, and has for its object to improve the jet structure of my former Patent No. 1,362,062,-dated December 14, 1920, whereby the stream of the flushing water is delivered from one side of the uple ata considerable distance above, instead of direetly from the bottom of the well, which together withtbe up-leg forms the water seal orktrap of the bowl. By thus positioning the jet openin the distance the water must flow to reach t crest of the dam is materially shortened, which tends to greatly quicken the siphon action of the closet But its greatest value lies in the elimination of the old jet structure, which according to my former nt, followed the usual practice of formthe jet openin in the bottom of the well e the bow l.,;and t on molding upon the under surface of said bottom a hollow clay part that communicates by a lateral with the usual Ely-passage that supplies water to the jet. This old structure has always been a source of more or less trouble, due to shrinka e checking or cracking, either during the ki 11 firing, or, by the action of frost in winter, and caused leakage and discarding'of thebowl. In the present case, the jet nozzle is disposed wholly within an external passage located at one si eof the bowl proper, dlschar es through the adjacent wall 'of the up-leg, w ich facilitotes the directing of a powerful jet in a di I course across said leg to create the z'ug-zag discharge referred to in the former patent. r

A further object of the invention is'to rovide a novel construction of bowl where y a normall open rearwardly extending housing is affor ed to receive and shield the oil-set or spud connections betweenthe flush't'ank and bowl, which connections heretofore have been exposed, and further to provide a housing which encloses and protects a hollow lip having apart which 'eooperates with the inlet chamber to direct water into the'latter as well as into the rimthat supplies the bowl interiot, the lip thereby functioning as a common supply for the rim and bowl.

T e various features and parts of the innation Will-be understood from the detailed description which follows, and by reference to the accompanying drawings, in which- 1 Figure 1 is a side elevation of a closet bowl, showing theexternal hollow rib. Fig. 2 is a broken side elevation showing the rib in section, also showing in section the jet passage within the rib. Fig. 3' is a central vertical longi/tudinal section, taken on line 33 of Fig, 4, showing the jet opening located in the up-leg of the discharge passage. Fig. 4' is a vertical cross-section .taken on'line 4-4 of Fig. 3. And Fi 5 is a broken to plan view of the bowls 0 Figs. 1 and 3, sl iowin-gthe siphon structurein section, also showing the rey imity of thejet opening to the crest of the dam, andthe course of the siphoning streamto and from said opening. 7 I In the drawings, the bowl 2 substantially conforms to the showing of my former patent, and com rises what is known as areversetype sip on jet closet bowl, 2 is theusual finshin rim, which receives the water from an inlet 0 amber 3, the latter in turn receiving the water from a rearwardly extending hole low lip 4, whichis disposed within a similarly progecting housing 5. The lip 4 is formed wit an upwardly facing opening 4 to which the usual oil-set or spudconnections leading from the flush tank (not shown) may be applied and hidden by the housing. 2a repr'e sents the up-leg of the siphon structure, by which the bowl isemptied. 2b is the downleg of said structure, which communicates with-the up-leg at the crest of the usual dam 6, vto form a continuous passage for the contents of the bowl to the soil-pipe via a bottom opening 20 (see Figs. 3, 4 and 5). I The forward end of the housing 5 is formed by the wall 3a and the adjacent bulge 5" of the down-leg 212. T e housing has a relatively large opening 7 at its rear end and the top of the housing, which forms a shelf, has an opening 3d to receivean -afford access to the off-set or spur connections, not shown, as above mentioned. A wallSb extends upwardly and forwardly from the top 8' of the lip and joins the wall 3a and forms together with the bulge 5" a passage 80 via which a portion of the water reaches therim 2; while theremzendm' ofhe Wate 7 sage, is

of the jet rib near the bottom end of the as-' taim'n flows into the hollow rib 7 and thence into the bowl. It will thus be seen that the housing 5 encloses and protects the lip 4, the lip not only conveying water into the rim 2 but also into the bowl interior, thus functioning as a common supply for the rim and bowl.

. One lateral wall 2d, of the discharge pasreferably disposed in plane, as est seen in Fig. 4, while the opposmg wall 2e bulges outwardly, as shown at 2;

in Figs. 4 and 5, for deflectlng a portion of the lip-flowing point by the After the said diverted portion of the discharge from the bowl'gravitates from the dam, it encounters an opposing bulge 240, which causes the stream to shoot, in the form of a sheet, across the bore of the down-leg and impinge the opposite wall 2d, as indicated bythe oblique dotted line a in Fig. 4. Thisdivides the down-leg momentarily into two chambers 03 and :v',the chamber :0 conany airthat may be present in the downg when the siphon action'starts, and preventsthe air from rising and destroying the siphonaction inaugurated by the flushing operation. The contents of the bowl thereafter continue to descend from the dam and form or build up a solid plug or mass of water in the chamber :21, and as its weight increases, the air trapped in chamber m be comes highly compressed, and is -finally forced downwardly into the soil pipe. j The portion of the flushing water that suplies t e jet in the resent case, gravitates oin the'inlet cham r3, or more particularly from an opening 4a-of the hollow lip 4, by means of an oblique hollow rib 7 that is imposed or molded upon the external surface of the wall 2d, as shown in the several views. to about the plane of the bottom of the well p, and within said rib is formed a smaller hollowrib 8,thelatterhaving a normally open lower end 8,and its upper end terminating at an openin 9, which is formed in the adjacent wall 2d 0 the a -le (see Figs. 2, 3 and 5). The'rib -8'is pre era ly disposed at an angle relatively to the longitudinal axis of the rib 7 in order to direct the jet diagonally across the up-le towards the point 2 as explained. y disposing the receiving end 8' sa e 7, the'discharge from rib 8 is efiFe'cte by su stantiall the full force of the flushing head, and the jet opening 9, being disposed in a higherthan normal plane, as compared with the older style jet openings of the well, the 'et is able to start the siphon action practica ly instantly. This, when taken with the means forentrapping and disposing of the atmospheric pressure in the down-leg, as explained, greatly accelerates the em tyin of the bowl, which is very desirable. e a (led a vertical discharge towards the said orce ofthe jet, as explained.

said hollow rib,

rib molded to said wall The rib' 7 extends fromthe' port 4a feature of the housing 5 and the lip 4 of the present case, is merely for the purpose of showing the adaptability of my novel and simple jet structure to the old, as well as to the latest improved standard siphon jet closet bowls.
